SHEET-METAL VENTILATION-WINDOW.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed. August 11, 1916. Serial No. 114,402.

To all whom it may concern:

Be it known that I, DARIUS E. SHRAUGER, a citizen of the United Statesof America, residing at Atlantic, in the county of Cass and State ofIowa, have invented certain new and useful Improvements in Sheet- MetalVentilation-Windows, of which the following is a specification.

My invention relates to windows in which the frames, adapted to be setpermanently in the walls of buildings, and the openable and detachedsash closures therefor are both made of sheet-metal; and the objects ofmy improvement are, first, to provide means for setting the sashpartially opened for ventilation, and still preserve the storm-prooffeatures of the closed windows; second, to afford facilities for openingthe window at both top and bottom simultaneously and retaining it thusopened; third, to facilitate the adjustment of size of such partialopenings; and fourth, to safely and. conveniently dispose of detachedglazed sash during a period of fully opened window. The above mentionedobjects with others hereinafter more fully disclosed are attained by thestructure and mechanism illustrated in the accompanying drawing, inwhich- Figure 1 is an outside elevation showing the glazed sash closed;Fig. 2, an inside elevation with the parts in the same position as inFig. 1; Fig. 3, a vertical section through the closed window andportions of the wall above and below showing in broken lines thedisposition of the glazed sash when the window is fully opened; Fig. 4,a plan or horizontal section of the closed window and adjacent wall ateach side in which the frame is set, taken on the broken line of Fig. 3;and Fig. 5, is a fragmenta'l vertlcal section showing the disposition ofthe glazed sash when the window is partly opened both top and bottom, inall of which views the same reference numerals refer to the same partsof the mechanism or structure.

The soffit or. head -7, is composed of a single strip of sheet-metal andhas an intermediate longitudinal portion bent downwardly upon itself toform the head stop 6. An outer edge portion is bentto stand upwardly andserve as the head casing 8.

The jambs 4 have each an intermediate vertical portion bent inwardlyupon itself to form the stops 5 and 5 coinciding with and mitered attheir top ends with the ends of the head stop 6. These stops are notcontinued to the foot of the jambs; the jambsheets below being split andlapped to take up the excess of width below the lower end of the stop;the space below the lower ends of the stops accommodate the ends of theoutwardly-inclined lip 12 of the bottom rail of the sash, as shown inFigs. 1 and 3. Outer edge portions are bent outwardly, into a planeagreeing with the outside face of the wall, to form the side casings 8and 8 having their top ends disposed back of the ends of the headcasing, as indicated by dotted lines in Fig. 1, and shown in Fig. 2.

Integral triangular extensions of the inner edges of the j ambs form thecheeks 18, standinginwardly from'the inner face of the wall, as shown inFigs. 8 andt. The lower longer edges of these extensions are bent toform the stiffening flanges 19 and 19, having their inner projectingportions doubled upon themselves for greater strength and smoothness. Across-bar 20, of sheet-metal doubled upon itself in cross-section, hasits opposite ends fastened to the top ends of the flange. The triangularextensions and crossbar form a rack or holder for the opened sash, aswill be hereinafter further described.

The sill of the frame is made of an integral strip of sheet-metal havingan intermediate portion adjacent to its inner edge bent upwardly to formthe longitudinal upstanding angular ridge 9, to properly weather thesill. A front edge portion is bent downwardly to a coincident plane withthe side casings, to which its ends are fastened, as are the otherportions of the sillends also fastened to the jambs, in the usualmanner.

The bottom rail of the sash, composed of a single strip of sheet-metal,has an intermediate portion bent upon itself to form the longitudinalupstanding flange 10, of double thickness, to back the bottom ends ofthe panes of glass. An adjacent parallel portion is bent upon itself toform the inwardly and downwardly inclined lip 11. The adj acent oppositeedge portions of the strip are bent to close flatly against each other,in an outwardly-standing base 29 beneath the lower edges of thepanes-which stand thereon,and are then bent to terminate in the doublelip 12 inclined outwardly and downwardly, to'closelonto the frame sillin front of the weather-angle 9, as shown in Fig. '3. V V v The stilesand munnion are substantially alike instructure; each is composed of asinglestrip of sheet-metal. A central longitudinal portion of the stripis bent equally upon itself from both edges, to form the 3 inner doubleflanges 13 of double thickness.

Adjacent opposite side portions are bent to stand outwardly at rightangles to and centrally of the inner flanges and closed flatly againsteach other to form a connecting web 30. And the remaining edge portionsof the strip are bent apart to form the outer flanges '14, standingoppositely inthc same plane;

they are thus spaced away from the inner flanges, by the web portion, toform at both sides, of munnion or stile, grooves to receive the edges ofthepanes of glass. In the stiles the outer grooves could receive thesprings, chains or cords for connecting weights or sash balances ofsliding windows. The inner 'top ends of the'stiles and munnion. Thiscompletes the sash members, leaving the grooves open at the top ends forthe insertion of the glass panes. A corner 15 of the top end of thesingle flange, is bent in above the glass to retain it in the sash. Thesash members, like those of the frame, are joined by mitering,interlapping, riveting 7 and soldering in the usual manner.

The inclined lips of the sash bottom-rail I form an angular grooveadapted to straddle the weather-angle 9, of the sill, thereby pivotingthe sash at the bottom, to allow the top to swing inwardly against theflanges 19 of the cheeks, or toclose outwardly against the stops 5 and6. Latch-buttons,

each'consisting ofa latch end 22 and an in- .wardly inclined thumbflange 23, are pive 'oted. intermediately near the top and on the v Vbacks of the stiles. Radial'slots' 21 through the cheeks receive theoutwardly swung I latch ends to set the inwardly swung top ofthe sash ata desired position for top ventilation. When these buttons are turned"vertically, as indicated by the dotted lines 24 in Fig. 2, the inclinedthumb flanges 23 are adapted to hook over the cross-bar 20,

to support the inwardly swung and upwardly slid sash for both top andbottom ventilation, as shown in Fig. 5. For smaller 7, op nspaces, bothtop and b t 'the'head edpins 26 are set in selected perforations 25 inthe lower'ends of the flanges 19 of the cheeks and the latch-ends of thebuttons reversed or swung downwardly and outwardly will engage anydesired slot to adjust the top opening. For full opening, the sash isdrawn upwardly entirely out of the frame, the groove of the bottom railis seated on the cross-bar 20, and the top of the sash, inclined againstthe wall above the frame, is secured by the bent button 28, as shown andindicated by dotted lines in Fig, 3.

I claim:
